TopMail

What it does

TopSend (also referred to as TopMail) is an email marketing platform that offers unlimited emails for $20 per month. It includes campaign management, transactional emails, automations, and a drag-and-drop editor. The platform is designed to be simple and affordable, with a built-in AI assistant to help write copy and set up campaigns. A key differentiator is its API built specifically for coding agents—AI agents like Claude or Codex can read the API reference page and integrate automatically without configuration files.

Who it is for

TopSend targets growing businesses and marketers who need a straightforward, cost-effective email marketing solution. It is especially suited for teams that want to leverage AI agents for automation and integration. The platform claims to be trusted by companies like MakerMilk, Shmoody, and Wubu. Pricing tiers include a free plan (5,000 emails/month) and a Pro plan ($20/month for unlimited emails), with an Enterprise plan for larger organizations.

Why it matters

Email marketing remains a critical channel for customer engagement and revenue. TopSend addresses common pain points: high costs (unlimited emails at a flat $20/month), complexity (AI assistant and simple analytics), and integration friction (agent-friendly API). The platform claims 99% deliverability via Amazon SES and includes features like A/B testing, e-commerce integrations (Shopify, WooCommerce, BigCommerce), and revenue tracking. For businesses already using AI coding agents, the one-click API integration could save significant development time.

Launch signal

TopSend won "Best in Show" at Launch Fest 2026, as indicated on its website. The Hacker News post (titled "Show HN: TopMail – LaunchFest Winner, $20/Mo Unlimited Email, Coding Agents API") suggests a recent launch with community interest. The website includes customer testimonials and a free trial offer, indicating active user acquisition.

Brand and naming

The brand name "TopSend" (or "TopMail" in the HN post) is straightforward and descriptive, suggesting top-tier sending capabilities. The dual naming may cause confusion, but both convey the core function. The tagline "Send unlimited emails. $20/month" is clear and value-driven. The brand positions itself as a simple, affordable alternative to complex platforms like Klaviyo, with a modern twist of AI agent integration.
